Current scheduling techniques used for cellular networks do not suffice for the emerging multi-rate systems like cdma2000 and High Data Rate (HDR). Real-time applications like video streaming must comprehend the channel conditions and consequently the data rates that are currently being supported; accordingly the content and the amount of data to be transmitted needs to be adapted to the availa...

This research investigates techniques for extreme scalable video rate transcoding. Traditional requantization based rate transcoding offers a reduction ratio close to 1:5. Unfortunately, the current bandwidth differential between Internet egress points easily exceeds more than 1:60. In this paper we present the analysis of a joint transcoder technique which combines requantization and re-tiling...
